kvm/openpic: in-kernel mpic support
Enables support for the in-kernel MPIC that thas been merged into the
KVM next branch. This includes irqfd/KVM_IRQ_LINE support from Alex
Graf (along with some other improvements).
Note from Alex regarding kvm_irqchip_create():
On x86, one would call kvm_irqchip_create() to initialize an
in-kernel interrupt controller. That function then goes ahead and
initializes global capability variables as well as the default irq
routing table.
On ppc, we can't call kvm_irqchip_create() because we can have
different types of interrupt controllers. So we want to do all the
things that function would do for us in the in-kernel device init
handler.
